Have too many Roombas and don’t know what to do with them? Instead of letting your cats ride on them or taking pictures of how they work, why not make a real-life Pac-Man game? Thats what a group of enterprising engineers from Colorado State University did with Roomba Pac-Man. In the game, a human controls Pac-Man using a joystick, and each ghost acts autonomously to find and chase our hero.

My favorite part is that the dots are actually bits of paper that the Pac-Man roomba has to physically vacuum up. [via hacked gadgets]
